Hook holes 23a and 23b are provided at the center of the side plate 2c of the base 2, and hanging metal fittings can be hooked on these so that the base 2 can be lifted by a crane or the like for installation and removal. It has become. Further, vertical split pipes 24a, 24b, 24c, 24d, which are partially cut out, are fixed to the inner wall portion 2d of the base 2 to support the lid 22 made of steel. As shown in the figure, the reason why the lid 22 is attached in the direction of the arrow or is removable is that the steel piece 15 is filled in the hollow portion 16. Further, the lid body 22 is provided with a round hole 27 for penetrating the support column 4 and small holes 29, 30, 31, 32 for installing a groove body 28 for improving strength and a blind. ing. The diameter of the round hole 27 and the diameter of the support hole forming body 3 are the same.

Next, the support column 4 will be described with reference to FIG. The column 4 has a circular tubular shape and is closed at the top. As described above, the column 4 is provided with vertically elongated elliptical holes 9 and 10 through which the bolts 12 can be inserted so as to face each other in the diametrical direction. . The vertically elongated hole 10 is notched in a wavy shape so that the height of the mounting position of the pillar 4 on the pillar hole forming body 5 can be adjusted. Mounting holes 33 and 34 for mounting the guardrail 5 are provided on the vertically long holes 9 and 10. Bolts 35 are inserted into these mounting holes and tightened with nuts 36 to connect and fix the guardrails 5.

Next, the installation of the temporary protective fence 1 will be described. As shown in FIG. 2, the base 2 to which the support hole forming body 5 is fixed is filled with the steel piece 15 to increase the specific gravity of the whole, and the lid body 22 is covered as shown in FIG. Next, as shown in FIG. 2, after inserting the column 4 into the column hole forming body 3 and adjusting the height of the column 4, the bolt 12 is inserted from the recess 14 of the base 2 in the lateral direction. The tip reaches the nut 13. Next, the bolt 12 is tightened with a tool so that the bolt 12 and the nut 13 are screwed together. Then, as shown in FIG. 1, the bases 2 are installed at predetermined intervals on the road, and the guard rails 5 are connected and fixed to the support columns 4 by the bolts 35 and nuts 36. In addition, the groove bodies 28 can be connected as needed.

Next, the removal and storage of the temporary protective fence 1 will be described. First, the bolt 35 and the nut 36 are unscrewed to remove the guardrail 5 from the column 4, then the bolt 12 and the nut 13 are unscrewed, and the bolt 12 is pulled out from the base 2 to form the column. Pull out the column 4 from the body 3. Then, the base 2, the columns 4, the guardrails 5 and the like are loaded on a truck and transported to a warehouse and stored. Since the base 2 has a rectangular parallelepiped shape, it can be stacked and does not occupy a lot of space, so that it can be transported and stored very easily. Then, at the next temporary installation, these should be transported to the temporary installation site and assembled. In this way, the temporary protective fence 1 can be used repeatedly as many times as desired.

Next, a second embodiment, which is a modification of the first embodiment, will be described. It is formed integrally by a mold without providing the hollow portion 16 in the base 2 and is simply configured as a whole. It is a thing. Specifically, instead of the support hole forming body 3, a support hole for receiving a support is provided in the iron base, and the bolt hole for receiving a bolt longer than the bolt 12 is orthogonal to the support hole, and A pair of recesses that are formed so as to penetrate through the center of the base and have the same shape as the recesses 14 are provided symmetrically in the diameter direction of the support hole on the surface of the base, and rainwater is discharged instead of the round holes 18 and 19. In order to do this, a vertical hole was drilled vertically from the support hole. To install a temporary protective fence, insert the support into the support hole, adjust the height of the support, and then insert the bolts laterally through the recesses on the surface of the base so that the tips of the bolts are on the base. Insert it until it comes out on the opposite surface, that is, until it reaches the other recess, tighten the bolt or nut with a tool, screw the bolt and nut together, install the base at a prescribed interval on the road, and then The nut is used to connect and secure the guard rail to the column. Explaining the dismantling of the temporary protection fence, first, unscrew the bolts and nuts to remove the guardrail from the post, then unscrew the bolts and nuts to pull the bolts out of the base, Remove the pillar from the. The effects of the second embodiment are almost the same as the effects of the first embodiment, but the manufacturing process is streamlined by integrally molding with a casting mold, and the work of filling the hollow portion with metal pieces and There is an advantage that the volume of the base can be further reduced by increasing the specific gravity of the base without the work of covering.

It is needless to say that the configuration of the present invention can be appropriately changed without departing from the gist of the present invention, and these changes are also included in the present invention as long as the technical idea is the same.
